Classification of soldering irons and precautions for using soldering irons
Soldering iron is an essential tool for every electrical maintenance personnel. Its quality sometimes directly affects the success or failure of component maintenance. Choosing an easy-to-use and inexpensive electric soldering iron is the voice of every maintenance personnel.
Soldering irons are divided into internal heating type and external heating type according to the form of heating tube
Small power is generally internal heating type, and relatively large power is mostly external heating type
The internal heating type, the electric soldering iron is smaller, and the power cannot be made very large. Most of the maintenance personnel use the internal heating type electric soldering iron.
The characteristic of the external heating type is that the heat is relatively concentrated. Some people once thought that the external heating type is not as safe as the internal heating type. Now the production process can meet the safety requirements. The quality of the electric soldering iron is good or bad, and the brand price is a decisive factor.
Soldering irons are divided into soldering table type and traditional type according to the style
The ironing table is more expensive and can be adjusted in temperature. There is a console, which takes up a lot of space and is inconvenient to carry, but it is easy to fix and use.
The traditional type is smaller, easy to carry around, with temperature adjustment, and some without pressure adjustment function.
Classification of soldering iron tips
A large part of the quality of the soldering iron is on the tip of the soldering iron. The tip of the soldering iron has a pointed shape, a horseshoe shape, a knife shape, and a straight shape.
Soldering iron tips are consumable items. After buying a good soldering iron, you only need to buy soldering iron tips in the future. If it is for home use, then a soldering iron tip can be used for ten or eight years without any problem.
By the way, solder wire is also a key. Now that you have bought a good soldering iron, you must buy a good solder wire. This is also a problem that cannot be ignored. Sometimes a good solder wire is more important than a good soldering iron. I use Elec, which is not the best brand, but it is still relatively easy to use. There are many brands of solder wire, such as domestic repairmen, Elek, and old A. Foreign ones are not recommended. expensive.
Precautions for using a soldering iron
1. When using a soldering iron, there must be a bracket. This is very important, otherwise it is easy to burn other things and cause danger.
2. The power of the soldering iron depends on the piece to be soldered. It cannot be a large horse-drawn cart or a small horse-drawn cart. This is about summing up experience in your own use. One principle is to choose high power for large parts and low power for small parts.
3. The use of the soldering iron mainly depends on the soldering iron tip, and the selection of the soldering iron tip is very critical.
4. When choosing a soldering iron, you must not buy a defective product at a low price. This is irresponsible to yourself and prone to electric shock accidents.
5. When using the soldering iron, it must be grounded. This is very important. First of all, it protects personal safety, and secondly, it is also a kind of protection for the soldered parts to prevent electric leakage from burning out electronic components.
6. Use good solder wire. Otherwise, a good soldering iron will be badly treated.
